microarray chips solidified biomacromolecules on the carrier, and then reacted with the target molecules labeled in the sample, and analyzed by specific instruments to obtain the content of the target molecules in the sample.
Microfluidic chips (biochips) are technologies that use microchannels (ranging in size from a few microns to a few hundred microns) to process and manipulate tiny fluids that can perform the functions of traditional analytical chemistry laboratories.
Therefore, the two are essentially different things, only because the name is particularly similar, it will be easy for people to link the two.
